May u please help me ill give out the brainly

Answers

Answer:

The answer is B.

Step-by-step explanation:

In order to solve this problem, you need to combine like terms, which in this case, are the x's. So, if you add the numbers with the x's together, you get 3x + 12y. The 12y remains untouched because there are no other terms with the same variable.

to identify the geometric sequence.

a n =  1.5 ⋅ 2 n − 1

Answer:

n x 2 = x

Step-by-step explanation:

This is the answer because:

1) 1.5 x 2 = 3

2) 3 x 2 = 6

The y intercept is 2.5 which can be written as 5/2

The slope is negative since it is going down and to the right and for every one square down it does 2 over so the slope is -1/2

That gives the equation y = -1/2 + 5/2

find the slope and y intercept for 15x= -2y-14

Answers

15x = -2y - 14
15 x + 14 = -2y
(-15/2)x - 7 = y
y = (-15/2)x - 7
Slope = -15/2
Y intercept = -7
